Fizi Territory is a territory located in the southern part of South Kivu Province, in the eastern region of the Democratic Republic of the Congo. Covering an estimated area of 15,789 square kilometers, it shares borders with Uvira Territory to the north, Mwenga and Shabunda territories to the west, Kalemie Territory of Tanganyika Province to the south, and Lake Tanganyika to the east, beyond the Ubwari Peninsula.

The Bembe people predominantly inhabit the territory, though it is also characterized by considerable ethnocultural diversity, with smaller ethnic groups such as the Babuyu, Babwari, and Bazoba residing in various villages throughout the area. Administratively, Fizi Territory is subdivided into four sectors: Lulenge, Mutambala, Ngandja, and Tanganyika. Its economy is primarily driven by agriculture, fishing, livestock farming, and artisanal mineral extraction. The Kyimbi (also known as Bendera) hydroelectric plant serves as a key source of power generation, although the territory's energy infrastructure remains limited. Other facilities, such as the Magembe and Nundu stations, ceased operation during the Second Congo War, whereas a small hydroelectric unit in Malikya, close to Baraka, remains active.

Fizi Territory landscape is dominated by mountainous terrain and a coastal plain along the eastern edge bordering Lake Tanganyika. This plain averages about two kilometers in width but widens significantly in the southern region, known as Kenya, where it reaches roughly twelve kilometers. In certain stretches, such as near Pemba and Luanga, the plain disappears entirely, leaving the lake's waters to crash directly against steep escarpments. The coastal belt extends from the Kambakulu River up to the Lweka River, which serves as the natural border between the Tanganyika and Mutambala sectors.

Inland, toward the center, south, and north of the territory, rises a vast plateau framed by parallel mountain chains oriented in a south–north direction. The highest peaks of these mountains exceed 2,500 meters in altitude and form part of the larger Mitumba range. The plateau descends abruptly to the east, overlooking Lake Tanganyika. The Lukongo summit, located near the administrative headquarters of the territory, stands at about 1,400 meters above sea level. The Baraka–Fizi road, which connects the lakeside city of Baraka to the interior, crosses a steep rocky escarpment reminiscent of the Nyangezi escarpment found in the neighboring Walungu Territory. Toward the west, the plateau inclines gently from east to west, a gradient that is mirrored by the flow of local rivers.

Major rivers and their corresponding sectors

The territory experiences varied climatic conditions influenced by altitude. The low-lying coastal plains are generally hot, with average temperatures around 35°C, while the middle and high plateaus are significantly cooler, averaging 24°C. Altitude in the territory ranges from approximately 750 meters near the lakeshore to 1,300 meters and up to 1,700 meters inland toward the highlands.

Administratively, Fizi Territory was established under the Belgian colonial ordinance-law of 8 August 1935. The original administrative center was located in Kalembelembe before being relocated to a settlement named Fishi—a name derived from the Kibembe language, later modified by colonial authorities to Fizi. The territory takes its name from this administrative center.

Fizi Territory is subdivided into four sectors: Lulenge, Mutambala, Ngandja, and Tanganyika. These are further divided into 18 groupements (groupings) and 132 localités (villages). The territory serves as an administrative unit responsible for the coordination, supervision, and support of state and provincial functions. Governance at the territorial level is overseen by a Territorial Administrator, who is supported by two Assistant Territorial Administrators. These officials are appointed by the President of the Republic upon recommendation from the Minister of the Interior and Security, Decentralization, and Customary Affairs, following proposals by the Provincial Governor. The Territorial Administrator acts as the representative of both the State and the Province, ensuring the operation of public services within the jurisdiction. Additionally, the Territorial Administrator and their assistants hold the status of judicial police officers with general jurisdiction and are empowered to requisition state services when required for the public interest. Regular administrative reports are submitted to the Provincial Governor and forwarded to the national Ministry of the Interior and Security, Decentralization, and Customary Affairs.
